Abstract
Mesoporous molecular sieves are promising as adsorbents for purification of biological molecules,such as amino acids,due to their tuneable
mesopore sizes and high surface area.In this study,the adsorption of the basic amino acid,lysine,onto MCM-41,a siliceous mesoporous
molecular sieve,has been investigated under a range of solution conditions.It was found to adsorb according to a Langmuir-type isotherm
with a maximum capacity at pH 6 of 0.21 mmol/g.The extent of adsorption depends strongly on the pH and ionic strength of the adsorbate
solution,due to a combination of ion exchange and electrostatic interactions governing the adsorption process.

摘要
介孔分子筛是有希望作为净化吸附剂的生物分子,如氨基酸,由于其tuneable
孔尺寸和高比表面积.在这项研究中,吸附的基本氨基酸,赖氨酸,到MCM - 41的,一个硅质介
分子筛,考察了下了一系列的解决方案的条件.结果发现吸附根据的Langmuir型等温线
最大的能力在pH值6 0.21毫摩尔/克的程度取决于强烈吸附的pH值和离子强度的吸附
解决方案,由于多种离子交换和静电相互作用执政的吸附过程.
